Coming to high altitude is no joke for many low-landers. The air feels “thin” because of how atmospheric pressure affects oxygen at high altitudes. Basically, the higher you go, the less pressure there is – thus the lower the concentration of oxygen, or the “thinner” the air will be.
The human body often reacts to the lack of oxygen with the following symptoms:
- Shortness of breath
- Loss of appetite
- Other unmentionables
